[K3] [Elecraft] in-band-IMD test

[e72x]

The Audio mod is a very simply! You just need to add simple two resistor
pararell on KIO3 module and replace one RFI choke! If anyone need mode just
send me mail and I will forward pdf direct !

73, E72X,



Alexander:

Sorry but I don't read Russian. What were the K3's AGC settings for the IMD
measurements? At a large input signal (S9+50 dB), using a "Fast" AGC time
constant will often result in poor IMD for conventional receivers using
analog type of AGC systems. I don't know the details of the K3's AGC system,
however.

Have you tried the S9+50 dB input signal with the "Slow" AGC setting?
